Download Managers

I don't know what made me come up with this, maybe its the fact it's 6 days till the end of the month and Ive used 93% of my dowloads. anway I was just thinking, I dont know if its possible I am no interent whiz, but it would be cool if there ws a program that could trick your ISP into thinking you arent downloading something when you reallay are.

I thought it was dogy, but down under, im with telstra have the unlimited downloads account, but when I go over 10gb, it doesnt cost me extra, instead they cut my speed down from 1500kb/s (<<not sure, it varies) to 16kb/s which is crazy.
